To all in/tom it may concern,

Be it known that I, LOUISA. HOERR, a citizen of the United States of America, re, siding at the city of St. Louis, Stateoflvlis' souri, have invented a certainnew and useful Brake Mechanism, of which the following is such a full, clear, and exactdescription aswill enable any one skilled in the art to which it appertains to make and use the same, reference being had to the.accompa nyv ing drawings, forming part of this specification. 1

My invention relatesto brake mechanism for railway cars and, more particu larly, to a ratchet device for connecting the handles of a brake to the brake staff.

The object of my invention is to produce a device of the class described which will be simple and strong in construction and reliable in operation, and which can be made with the smallest possible amount of machine work. I i

In the accompanying drawings, which illustrate one form of brake mechanism made in accordance with my invention, Figure 1 is a vertical central section; Fig. 2 is a cross section; and Figs. 3 and dare plan views of details of construction.

Like marks of reference refer to similar parts in the several views of the drawings.

5 is a brake staff provided on its upper end with a square portion 6 adapted to enter a socket 7 formed in a castingS. The casting 8 is preferably held on thestaff by means of a pin 9 passing through the said casting and the square portion 6 of the brake staff.

The casting 8 is hollow and has formed on the bottom of its interior inclined teeth 10 which form one part of the ratchet mechanism. Resting upon the casting 8 is a cen- 1 tral casting 11 having a downwardly projecting angular portion 12 provided with a central opening 13. Surrounding this angu lar portion 12 is a wheel 14, shown in detail in Fig. 3. This wheel 14 is provided with a square opening 15 to receive the part 12 and it provided on its under face with inclined teeth 16 which engage with the teeth 10 on the casting 8. The casting 11 has formed on its upper face teeth '17 which may be similar to the teeth described in my prior application, Serial No.- 807,i13, filed December 8, 1913, and, like the teeth therein described, may be engaged by a swinging handle .18 pivoted at .19 to a housing 20'surrounding the two castings 8 and 11. The parts are Specification of Letters Patent. Pwbgntgd 3'53; 12, 1915, Application filed August 24,1914. Serial no. 858,250.

held in position in the housingQO. by means of an annularmember2l secured to the housing by rivets 22. In order to hold the upper casting 11 centrally in the housing 20, I providethe said housing with a depending in 23 adapted to engage with the opening 1 3 in the casting 11. r

The operation of my device will be evident. The handle 18 is thrown into engagement with the teeth 17 in the upper face of the casting ll'and said casting is then oscillated by means of the handle. When the handle moves in one direction, the parts 8 and 11 will rotate relatively, the wheel 1% being simply raised by contact with the teeth 10 on the casting 8. lvVhen, however, the

handle is moved in the opposite direction, the parts are firmly locked together and rotate as one piece.

It will be evident that my ratchet connection is simple in construction and very strong. At the same time, the form of the parts is such that all of the parts may be formed by castings without any machine work whatever.

While I have shown the connection between the handle and one part of the ratchet I as like that in my prior application above referred to, I do not wish to limit myself to such .form of connection, as it is evident that the upper part of the ratchet mecha nism may of handle.

Having fully described my invention, what I claim as new and desire to secure by Letters-Patent of the United States is:

I 1. In a brake mechanism for railway cars, the combination with a brake staff, of a be engaged by any suitable form member carried by said staff and non-rotatable with respect thereto, said member being provided with ratchet teeth on its upper face, a second member arranged above said first named member, a handle adapted to be thrown into and out of engagement with sald second named member, and a tl'lllCl' member mounted to move vertically with respect to said second named member but to be incapable of rotation relative thereto, said M third named member being provided with ratchet teeth normally held in engagement with the teeth on said first named member by gravity.

2. In a brake mechanism for railway cars, the combination with a brake staff, of a member carried by said brake staff and nonrotatable with respect thereto, a second memthe combination with a brake staihof a mem-' ber, a handle adapted .to be thrown into and out of engagement with said second member, and a third member carried by said'sec- 0nd member and having ratchet engagement,

With said first named member, all three of said. members being capable of rotation in either direction with the stall when the handle is out of engagement'with said sec- 7 0nd named member. 7 I p 3.}Ina brake mechanlsm for lfl-llWZLY-CillS,
